To find the common factor that Steven can use to factor the expression 42xyz + 56xy - 7x, we need to look for the greatest common factor (GCF) of all three terms: 42xyz, 56xy, and 7x.
First, let's list the factors of each term:
Factors of 42xyz: 1, 2, 3, 6, 7, 14, 21, 42, x, y, z, xy, xz, yz, xyz
Factors of 56xy: 1, 2, 4, 7, 8, 14, 28, x, y, xy
Factors of 7x: 1, 7, x
Now, let's identify the common factors among these three lists of factors:
Common factors: 1, 7, x
So, the possible common factors that Steven can use to factor the expression are 1, 7, and x.
